T 0 all whom it may concern:

Be it known that l, lilii-inroN W. SToMs, a citizen of the United States, residing Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Condensers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tornake and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a refrigerating apparatus and particularly to a condenser for converting a refrigerant from a gaseous phase to a liquid phase.

The condenser is so constructed that there will be a constant supply of available refrigerant in the liquid phase to entrain or co-mingle with refrigerant in the gaseous phase so that the refrigerant in the gaseous phase will readily condense into the body of its own liquid which has been previously cooled and be thereby rendered available for introduction into an evaporator in the room or about the zone in which the temperature is'to be reduced.

The condenser comprises a unitconsisting of'a plurality of pipes horizontally superposed one above the other and sub-divided into a flooded section or liquid reservoir, a condenser section and a final cooling section, from the bottom toward the top in the order named and if desired I may arrange atthe lowermost point in the unit a precooling section for the refrigerant in the gaseous phase so that its temperature will be reduced before it combines with the refrigerant in the liquid phase and thereby more readily condense;

I have arranged the various pipes or sections of the unit in horizontal, vertical alignment and I prefer to provide an upward flow so that the cooling pipes containingthe refrigerant for the final cooling will be next to the condensing): watervat its source I and thereby be able to avail itself of the lowest temperature of the cooling water, thereby reducing the refrigerant to substantially the temperature of the cooling water before it enters into the receiver or before it enters into the evaporator.

The novel construction of the invention will be specifically described hereinafter, reference being had to the accompanying drawings, in which Fig. l is an elevational view of a refriger ating plant constructed in accordance with my invention.

Fig. 2 is a vertical, longitudinal, sectional view through the unit, and

Fig. 3 is a similar view of a slightly modified form of unit.

In order to comprehensibly describe the invention 1 have shown part of a simple form of refrigerating plant.

Referring to Fig. l, 1 designates a gas compressor having; an inlet at 2 and an outlet at 3. i is a receiver or refrigerant reser voir to receive the refrigerant in the liquid phase. 5 is a discharge for the receiver communicating with the evaporator coils 6, which discharge into t compressor through the inlet 2. The liquid is drawn through the coils 6. absorbing the heat in the usual way and becoming automatically converted from a liqull phase into a gaseous phase in which state it enters the compressor 1. The compressed gas is dischara'ed through the port 3 into a pipe 7 which communicates with a gas pro-cooling section or pipe 8 of the unit, there beina stop valves 9 and 10 shown for the pipe 7. which may be used to close communication hroueh said pipes.

The gas pro-cooling:- pipe 8 terminates in a directional flow nozzle 11 which discharges into a pipe 12, the lower end of which is in communication with the flooded section of the condenser consisting of the pipes 13, 14, 15, 16 and 17. The top end 18 of the pipe 12 communicates with the lower pipe 19 of shown as consisting of the pipe 12, the pipe 19 and the pipes 20 and 21. The top of the condenser, that is, the pipe 21, communicates with the top pipe 17 of the flooded section or reservoir through the medium of a pipe 22 where the refrigerant in the liquid phase divides and the amount of liquid equal to that which has been condensed from the gaseous phase to theliquid phase will pass upwardly through the pipe 23 to the top of the final coolingsection of the condenser consisting" of the pipes 24, 25 and 26 and discharge through the flow pipe 27, having its discharge connected to the intake 28 of e condenser section. the condenser being receiver e, T final cooling s be provided w purge pipe 29, as will. be well u derstood and drain 30 mm a be prov ded for the seccion 8 so that the condenser may be drained and the contents may flow into pipe 27 and pass into the receiver 4.

Above the unit or condenser is a source oi cooling liquid supply 31, which may be an 1O e onmted t oi 'o )DllQCl by a suitable pipe 32 thrc which he cooling liquid,

for example, w or, may iill the trou flow over the 1 pcs as 'is common .Jith suriace cc sers.

It is to be understood that the passage of the entrained gas is progressively upward so some is absorbed by the cooling water at tie bottom but the cooling wat r becomes progressively cooler toward the to this being" important feature since it is desirable to have the refrigerant at the lowest temperature at the receiver, which would not be the gas entered pipe 24 first Lro'orcssively passed downward.
